CORPORATION OF NEW YORK MACHINE FOR DRYING RANDOM COLORED YARN ON THE GONE Application led September 2l, 1926,' Serial No. 136,809. Renewed April 16, 1930.

This invention relates to a method of and apparatus for drying yarn which has been partially colored on hollow perforated cones or cores by causing a coloring liduid to pass through the' portions of the yarn registering with the perforations as shown in my pending applications Serial No. 66,533, filed November 3, 1925, and Serial No. 109,930, filed May 18, 1926, or by any other method Where-v ,10 by the application of coloring matter to the yarn leaves the Whole or portions of the mass of yarn in a more vor less moistened or dampcned condition.

The main object is to provide a simple, economical and eiiicient method of and means f :t'oreffecting a more expeditious drying of the moistened portions of the yarn lon the cone or bore than has heretofore been practiced by passing heated air through the moistened portions of the yarn registering with the perforations in the core immediately following the coloring operation so that the dryf spotted yarn may be knit or otherwise worked into a fabric within a relatively short time after the coloring operation as compared with the time usually required for such purose.

p In other words, I have sought to expedite the drying of the yarn upon-the same bobbin or spool upon which it has been previously colored.

Another object isto utilize the heat developed by the operation of the air feeding and forcing means for heating the air as it is delivered by said means'tov the previously colored yarn.

A further object is to provide means whereby the perforated cores or bobbins upon which -featuresof the invention will be brought out heated air is supplied by a suitable air compressor. Y

Figure 2 is a front elevation, partly in section, of the apparatus shown in Figure 1.

Figure v3 is an enlarged horizontal sectional View taken on line 3 3, Figure 2.

Figure 4 is an enlarged transverse "vertical sectional view of the air compressor andl adjacent vportion of the pipe leading therevfrom.

Figure 5 is an enlarged detail sectional View, partly in elevation, of one of the screw supporting heads carried by one of the air delivery nozzles for receiving and supporting a perforated core or. bobbin u on which the,

yarn is wound when subjectsy to the drying operation. y

Figure 6 is a top plan ofC a modiediorm of yarn drying apparatus in which the de-A livery nozzles are mounted upon a circular f pipe having radial branches communicating rotary gear type having a case -A- provided with an air inlet -'-a-,- and an outlet pipel '-a,-, said pump being valso provided with a pair of lco-operative air compressors -r-B- V- rotatably mounted within the case -A-between the inlet and outlet a-.for compressing the air admitted through the opening zzand ,forcing it outwardly through the outlet -a'- in the manner wellknown in this type of compressor.

The impellers -B-. are mounted upon eachother by gears ,-fb-, one of said shafts to be'belted to any available source of power, not shown. f

As illustrated, in Figures 1 and-2, the apparatus also comprises a horizontal header pipe -1- which is connected intermediate its ends to the outlet pipe -aof the compressor case .A- and its outer ends closed l y suitable plugs -2-.

Rising from the ends an intermediate portion of the header pipe -1- is a series of upright pipes which are closed at the top by caps -3- and are each provided intermediate their lower and upper ends with a ries of relatively smaller branch pipes or delivery l its other end closed while its intermediate .portion is provided with an annular enlargement or .head -5- for receiving and supporting the perforated core dof the yarn cone -D- as shown more clearly in Figure 3.

Each delivery nozzle -4- is preferably madein two sec-tions -4- and -4- arranged end to end and having their adjacent ends threaded externally and screwed into a central socket in the corresponding head -5- to facilitate the assembling of those parts and also to permit the use of heads of different sizes as may be required for different sized cores d-, the section -4- being tubular from end to end while the section -4- is only partially tubular from the end adjacent the section -4- and is provided with radial openings ,-6- leading from the interior of the hollow end adjacent the section -4- and just at the inside of the head 5 and between said head and the free end of the section -4 to permit the passage of heated air from the upright pipe -3- through the pipe section -4- and thence into the adjacent hollow end of the section -4- where it is free to pass through the branch openings -6 into the perforated core The cores -dare preferably conical, their larger ends being opened while the smaller ends are more or less closed by contraction, said cores being usually made of relativel. sti paper or cardboard and are provide intermediate their ends with radial apertures -fdsarranged at suitable intervals circumferentially' and lengthwise of the core to permit the passage of air therethroughl to the registering portions of the yarn wound thereon after the yarn has been colored by a suitable coloringliquid which is passed through the apertures and registering portions of the yarn.

As shown in Figure 5 each head -5- is provided with a conical periphery having a s'piral thread 7 upon and with which the larger end of the conical core is adapted'to be mounted and engaged with a turnilig or screwing motion so as to firmly hold the core on the nozzle while the heated a1r under pressure is being forced into the interior of the core and outwardly through the perforations -cland registering portions ofthe yarn.

The nozzle section -4- extends some distance beyond the corresponding head -'-5-` so as to project a corresponding distance into the interior of lthecore -dwhen the latter is placed upon the head -5- or nozzle -4-, the inner of saidsection -4- being provided with a valve or plug -8- adapted to engage the inner walls of the coren at or near the small end thereof and some distance from the head -5- to prevent escape of the heated air through the smaller end of the core in case it should be more or less open and thereby confining the heated air between said valve or plug and the head 5 except as it is 'permitted to escape from the passages 6- through the apertures -dand thence through the registering portions of the arn D-.

T e nozzles -4- of each upright pipe -3 radiate therefrom atv an angle of substantially 90 degrees so as to permit at least two vertlcal rows of yarn cones to be mounted thereon for drying at the same time, it be-I ing understood that a corresponding number ofyarn cones will be mounted upon the nozzles of each upright pipe thus permitting a simultaneous drying of a large numberof kpreviously colored yarn cones.

In Figures 6 and 7 the nozzles -4- are secured to a' circular pi e -3- so as to radi ate therefrom prefera ly in outwardly and upwardly inclinedv planes at regular intervals throughout the circumference of the pipe -3. o

This circular pipe -3- is connected by inwardly extending radial branches -1- to the discharge pipe -aof the pump case -A- whereby the air which is heated in and discharged from the pump is forced through the branch pipes -1- and thence into the circular pipe -3- from which it is delivered through the nozzles -4- into the corresponding perforated cores and thence outwardly through the perforations d'- and registering portions of the yarn -D-.

The perforated cores -d--withl the yarn thereon are mounted upon the nozzles llon the pipe ring -3- in substantially the same manner as previously described for the nozzles on the upright pipes -3- while the nozzles on the ring 3- are arranged circumferentially uniform distances apart suilicient to permit the yarn cones to be easily placed thereon and removed therefrom when desired.

Operation The perforated cores a`5 with the previously colored and more or less moistened yarn thereon are placed' upon the several nozzles -4- or rather upon their respective heads -5- whereupon the action of the pumps of the rotary members -B- of the pump draws the fresh air into the pump case -A- and heats the air to a pre-determined degree by reason of the compression thereof, said heated air being then delivered through the corresponding pipe system and thence into the several nozzles -4-- from which it passes through the perforations d and outwardly through the registering portions of the yarn -D- thereby effecting a quick drying 'of the/ previously colored portions of the yarn, the time required for complete drying of the colored portions of the yarn being dependent somewhat upon the temperature of the air delivery to the nozzles by the pump Care must be taken however to keep the temperature of the air sufficiently low to prevent burning or charring of the yarn and paper core upon which it is wound.

Otherwise the operation will be clearly understood from the foregoing description taken in connection with the accompanying drawings.

It will be observed that the outer end faces of the threads 7 are more abrupt than the inner faces for effecting a firmer grip upon the paper cones when screwed thereon.

What I claim is: i

l. In an apparatus for drying'yarn on a perforated conical core which is open at its larger end, a frusto-conical plug for the larger end of the c'ore and means for passing air through said plug to the interior of the4 perforated core and thence outwardly through the perforations and through the yarn.

2. In an apparatus for drying yarn on a perforated conical core which is open at its larger end, a rod extending into the core through its larger end and containing a central air passage and radial openings therefrom within the core, and a frusto-conical plug fixed on said rod and closing the larger end of the core.

3. In an apparatus for drying yarn on .a perforated conical core whose larger end is open, a rod extending into the core through its'larger end and containing a central air passage and radial openings therefrom within the core, and 1u s fixed on said rod at opposite sides o sald radial openings for closing the larger and smaller ends ofthe core.

4. A holder for` a cone of arn, com rising a frusto-conical mandrel aving a s arp projecting screw thread whose surface faclng toward the larger end of the mandrel is perpendicular to the axis of the mandrel and whose other surface is inclined, so that the screw thread takes a firm grip on the interior of the cone and draws it upon the mandrel on relative rotation of the mandrel and the cone.

5. In an apparatus for drying yarn wound on a perforated conical core which is open at its larger end, a frusto-conical plug for the larger end of the core, a screw thread having spaced turns projecting from the frustoconical surface of the plug and adapted to draw the inner surface of the core ti htly against the frusto-conical surface o the plug on relative rotation of the core and plug, and means for passing air through said plug into the interior of the perforated core and thence outwardly through the perforations and through the yarn.

6. Inan apparatus for drying yarn wound on a perforated conical core which is open at its larger end, a frusto-conical plug having a sharp projecting screw thread whose surface facing toward the larger end of the plug is perpendicular to the axis of the plug and whose other surface is inclined so that the screw thread takes a firm grip on the interior of the core and draws it tightly against the plug on relative rotation of the plug and core, and means for passing air through said plug into the interior of the perforated core and thence outwardly through the 'perforations and through the arn.

y vIn witness whereof I have hereunto set my hand this 16th day of September, 1926.
